PROGRESS stack trace
Exception code: C0000005 ACCESS_VIOLATION
Fault address: 77FCB9B1 03:000009B1 C:\WINNT\System32\ntdll.dll
CAUSE:
GET-BYTE and GET-STRING do not properly guard against reading memory past the end of the memory allocated for the MEMPTR. Those functions should return the unknown value (?) in those cases, according to the documentation
CAUSE:
Bug# 20000121-024
FIX:
Upgrade to Progress 9.1D
